W纤维增强W/铜复合材料被设计为CuCrZr热沉材料和W等离子体面对材料之间的过渡层。提出了一种燃烧合成与离心渗透相结合的制备W纤维增强W/Cu复合材料的新方法。铝热剂反应产生的瞬变温度超过2000℃的铜熔体在高重力场的帮助下渗透到钨粉和纤维床中。研究发现，由于铝热剂反应产生的高温，W颗粒被烧结并结合到W纤维上。W纤维增强W/Cu复合材料的弯曲强度提高了12.7%。(C)爱思唯尔出版的2014年。
W fiber reinforced-W/Cu composite is designed as a transition layer between CuCrZr heat sink material and W plasma facing material. A novel method was developed for the preparation of W fiber reinforced-W/Cu composite by combining combustion synthesis with centrifugal infiltration. Cu melt with a transient temperature over 2000 degrees C produced by the thermite reaction was infiltrated into the W powder and fiber bed with the assistance of a high gravity field. It was found that the W particles were sintered and bonded to the W fibers due to the high temperature produced by the thermite reaction. The bending strength of W/Cu composite improved 12.7% through W fibers reinforcement. (C) 2014 Published by Elsevier B.V.
